IPoster: Scleral Lenses in Current Ophthalmic Practice Evaluation: Patient Demographics, Indications and Lens Designs

Purpose: This multi-center study reports demographics of scleral lens wearers and scleral lens prescription patterns as reported in an online survey.

Methods: An online survey was conducted from December 13, 2016 to March 31, 2017. Scleral Lens Education Society members were invited to participate via e-mail, links to the survey were posted on the Scleral Lens Fitters Facebook page and were included in two monthly online newsletters. Fitters were asked to provide information about their most recently evaluated established scleral lens patient (history of ≥ 6 months of lens wear). We describe demographics of scleral lens wearers, indications for wear, and lens designs prescribed.  

Results: We received 376 responses.  Mean patient age (n=339) was 44 ± 14 years (range 9-86 years). Male gender was reported in 62% of patients (n=352). Primary indications for scleral lens wear (n=312) were corneal irregularity (84%), ocular surface disease (7%) and correction of refractive error (5%). Median lens diameter was 16 mm (range 10-23 mm) for both right (n=207) and left (n=212) eyes. Single vision lenses were prescribed for 97% of right eyes (n=207) and 98% of left eyes (n=211).  Right lenses (n=201) incorporated spherical (69%), toric (28%) and wavefront-corrected (3%) optics.  Left lenses (n=207) incorporated spherical (70%), toric (28%) or wavefront-corrected (2%) optics.  Right lenses (n=201) featured spherical (61%), toric (28%), quadrant-specific (8%) or impression-based (3%) haptics.  Left lenses (n=207) featured spherical (63%), toric (27%), quadrant-specific (7%) or impression-based (2%) haptics.

Conclusion(s): Scleral lenses are most commonly prescribed for management of corneal irregularity. Median lens diameter prescribed is 16 mm. Most scleral lenses feature single vision optical correction, and a majority of lenses prescribed feature spherical optical power and haptic designs.
